674560 - ESAB 7-Pin Square Flange Receptacle - Shell 23 Control Connector

Technical Overview of the ESAB 674560 Connector

The ESAB 674560 is a specialized electromechanical component designed for the rigorous demands of industrial welding environments. Identified as a CONN SQ/F REV *7C SHELL 23, this part is a multi-pin circular connector utilized primarily for control signal transmission between power sources and auxiliary equipment such as wire feeders, remote controls, and automation interfaces. The designation indicates a Square Flange (SQ/F) mounting style, which provides a robust four-point attachment to the machine chassis, preventing rotation or loosening due to the high-vibration conditions typical of heavy fabrication shops.

This connector features a Shell Size 23 housing, a substantial size that allows for durable insulation and spacing between its 7 Contacts (7C). The "REV" likely denotes a reverse arrangement, often implying the gender of the contacts (sockets vs. pins) or the insert rotation relative to the keyway, ensuring that incompatible cables cannot be mated accidentally. Maintaining the integrity of these connections is vital; a compromised connector can lead to intermittent arc control, wire feed stuttering, or complete loss of remote functionality.

As a genuine ESAB spare part, the 674560 is manufactured to precise tolerances. The contact materials are selected for high conductivity and resistance to oxidation, while the shell material is engineered to resist impact and thermal stress. For maintenance personnel and industrial electricians, replacing a damaged chassis connector with this exact OEM specification ensures that the IP rating (if applicable to the mated pair) and mechanical latching properties are preserved, safeguarding the machine's internal electronics from dust and moisture ingress.

Application and Compatibility

This connector is typically found on the front or rear panels of ESAB industrial power sources. It serves as the interface point for control cables that carry low-voltage signals (potentiometer data, trigger signals, etc.). When troubleshooting communication errors between a welder and its feeder, this receptacle is a critical check point. Replacing a worn or arced connector with the 674560 restores factory-level reliability to the system.
